An improved aqueous electrocoating composition containing an anticrater additive which is a reaction product of silane component based on glycidoxy propyl tri methoxysilane and poly oxy propylene diamine. Materials were studied by infrared spectroscopy and particle size analyzer. Crater number of electrocoated sample was evaluated by GM9532p standard. The final electrocoat contains anticrater a...

fiber post (GFP) treated or not with phosphoric acid, silane coupling agent, and unfilled resin. GFPs were etched or not with 37% phosphoric acid and different surface coating applied: silane coupling agent, unfilled resin, or both. Composite resin blocks were built around a 4-mm height on the GFP. Unfilled resin (20 s) and composite resin (40 s) were light activated by a light-emitting diode u...

The linear thermosensitivity of colloidal crystals immobilized in a copolymer hydrogel film composed PNIPAM and PNMAM could be enhanced by chemically binding them on glass substrate using silane coupling agent.

in this research, effects of concentration and time of silane treatment of rice straw flour on the morphology and mechanical strengths of rice straw flour/polypropylene composites were investigated. tri ethoxy vinyl silane (c8h18o3si) with 98% purity in two concentrations of 5 and 10%, that each concentration had two immersion times including, 45 and 90 min for using treatment rice straw flour....

This study focuses on the preparation of Ni-plated polystyrene (PS) microspheres (diameter 3.7–4.5 μm). These Ni-plated PS microspheres have core–shell structures that were designed and prepared using an organic polymer core (PS with 3-(trimethoxysilyl) propyl methacrylate (TSPM)) and an inorganic metal (Ni) plated shell. The polymer microspheres were synthesized by dispersion copolymerization,...

The aim of this study was to compare the effects of various porcelain surface-conditioning techniques, used either alone or in combination, on the shear bond strength (SBS) of ceramic brackets cured with a light emitting diode (LED). Thirty glazed porcelain facets were randomly divided into three groups of 10. In group I, the porcelain surfaces were etched with 9.6 per cent hydrofluoric acid (H...

OBJECTIVES Esthetic posts have been developed to maximize the foundation of esthetic restorations. The purpose of this study was to evaluate the effect of silane on the bond strength of three fiber-reinforced resin posts (fiber posts). METHODS Fifty-four extracted human maxillary central incisors and canines were endodontically treated. D.T. Light Post (DT, Bisco), FRC Postec (FR, Ivoclar Viv...
